Description

The present invention relates to a machine for making bundles of sheets, in particular signatures, wrapped by means of a wrapping machine.
Machines for making and wrapping bundles of sheets are already known, in particular it is cited the US Patent 3,579,944 that refers to an apparatus and method for banding bundles of envelopes, with the following drawbacks: the bundles are not completely guided during the movement toward the banding station, with the negative consequence that the bundle is broken up.
Furthermore the structure of this machine requires a large space.
The object of the present invention is to eliminate the above drawbacks and to provide a machine, for making bundles of wrapped sheets, having the following characteristics :
  • the bundles of sheets are always kept guided, so that when the bundles are pushed towards the wrapping machine they can freely slide without tripping and therefore without breaking up;
  • one or more parallel wrappings can be effected on each bundle by means of a single wrapping machine;
  • the bundle is correctly positioned at the wrapping machine without interfering with the wrapper by tearing it or by sticking into the wrapper guiding groove.
  • These characteristics are all achieved by the present invention as pointed out in the enclosed claims.
    The following detailed description of the machine includes three preferred but non-limiting embodiments of the machine, illustrated for merely exemplificative and non-limitative purposes, in the annexed drawings wherein:
  • Fig.1 is a schematic side view of the machine, in an intermediate step of the operating cycle;
  • Fig.2 is a schematic side view of the machine, in a second step of the operating cycle;
  • Fig.3 is a schematic plan view of the machine, in the step of the operating cycle of fig.2;
  • Fig.4 shows an enlarged detail of fig.3;
  • Fig.5 is a second embodiment alternative to the embodiment illustrated in the preceding figures;
  • Fig.6 is a third embodiment alternative to the preceding ones;
  • Fig.7 is a schematic side view of the wrapping machine with the bundle in a first position;
  • Fig.8 is a schematic side view of the wrapping machine with the bundle in the wrapping position; and
  • Fig.9 is a plan view of the wrapping machine.
  • The present machine generically includes means for transporting said sheets, for making subsequent bundles of sheets and for positioning said bundles at a wrapping machine.
    With reference to the enclosed drawings, said means are defined in the following way, as an example:
  • said transporting means consist in a feeder 1 of the sheets 2 and similarly the means for making the bundles 3 of sheets 2 consist in a support 4 which is progressively lowered by a piston 5 as the forming bundle 6 of sheets 2 grows, until support 4, consisting in horizontal bars, goes below a first pusher 7 shaped as a rack made up of horizontal and vertical bars 8. The bars of support 4 pass through bars 8 of support 7 while lowering, whereby !he incoming sheets are laid on the upper surface of pusher 7, which during the backstroke to its rearmost position, by means of piston 9, lays down a portion of the forming bundle 6 on support 4 which progressively lowers until it reaches the plane 11 of rollers 12, prior to the shifting of bundle 3 towards stop 10 in the direction of arrow A. As it may be seen in fig.1, which is an intermediate position of the cycle, the forming bundle 6 of sheets is formed on support 4 while piston 9, through pusher 7, pushes the previously formed bundle 3 against stop 10, reaching the position of fig.2.
  • Support 4 returns from the lower position to the upper position of fig.1 by means of the piston 5, in order to collect other sheets coming in from feeder 1 when pusher 7 moves from the position of fig.2 to the rearmost position.
    The means for transporting said sheets and the means suitable for making subsequent bundles of sheets could be arranged even in a manner different from the one described above and given as a mere example.
    A second pusher 13 is provided, which pushes each bundle 3 by means of a piston 14 in the direction of arrow B, as in fig.3, perpendicular to arrow A until it is positioned at a wrapping machine 15 arranged side by side with the machine, as shown in fig.8, in a position suitable for wrapping bundle 3 with a wrapper placed in groove 16 of the wrapping machine 15, so as to wrap the bundle with the wrapper transversely with respect to the direction of motion of said second pusher 13.
    Pusher 13 is stopped in multiple positions during its travel for shifting bundle 3 towards the wrapping machine 15, in order to wrap the bundle with multiple wrappers.
    A further characteristic of the present invention is the provision of means suitable to keep the bundle pushed against said stop 10 even when the first pusher 7 moves away from the bundle to return in the rear position suitable to move subsequently a new bundle in the position against stop 10, as shown in fig.2.
    In a first embodiment, said means suitable to keep the bundle of sheets against said stop 10 consist in a series of cylindrical or rounded pegs 17, vertically pushed by a piston 18 as shown in figs.3 and 4, passing through the vertical bars 8 of the first pusher 7 so as to fill the spaces therebetween and thus achieve the free sliding of bundle 3, pushed by the second pusher 13 towards the wrapping machine 15, along said pegs 17 while keeping the bundle pushed against the stop wall 10 when pusher 7 returns to its rearmost position, according to arrow C.
    A second embodiment of the means suitable to keep the bundle pushed against said stop 10 is illustrated in fig.5, according to which the horizontal plane 11 formed by rollers 12, on which the bundle of sheets arrives, is inclined around a pivot 19 integrally with said stop 10 so that a vertical plane 20 can be raised without interfering with the bundle of sheets which is inclined integrally with said horizontal plane 11 during its inclination. Therefore, the vertical plane 20 keeps the bundle pushed against said stop 10 when the first pusher 7 moves away from the bundle to reach its rearmost position. In this way, the vertical plane 20 and stop 10 back in the vertical position form a channel along which bundle 3 is moved by said second pusher 13, after that said roller plane 11 pivoted in 19 has regained its original horizontal position from the inclined position.
    A third embodiment is illustrated in fig.6, according to which a plane 20', which may be solid or bar-shaped, is raised in an inclined position by piston 18' so as to avoid interference with bundle 3. When pusher 7 is returned according to arrow C, plane 20' resumes the dotted vertical position against bundle 3, during the shifting of bundle 3 towards the wrapping machine.
    A further feature of the machine is the provision for a plate 21 adjacent to the wrapping machine 15 and suitable to be inclined around pivot 22, by means of a piston 23, from the horizontal position to a position high on the side of the wrapping machine 15, as shown in fig.7. In this way, when the bundle 3 of sheets 2 is pushed by said second pusher 13 towards the wrapping machine 15, the bundle can freely slide with no hindrance and climb over groove 16, in its front portion, until the bundle is in the correct position, as shown in fig.8, to be wrapped by the wrapper of said wrapping machine 15 when plate 21 is taken back to the horizontal position.
    The wrapping machine 15 may also be moved parallelly in different positions, so that, if required, various parallel wrappers corresponding to the different positions reached by the wrapping machine 15 can be wrapped around the bundle.
